Enum rapid_qoi::DecodeError

pub enum DecodeError {
    NotEnoughData,
    InvalidMagic,
    InvalidChannelsValue,
    InvalidColorSpaceValue,
    OutputIsTooSmall,
}

Errros that may occur during image decoding.

Variants

NotEnoughData

Buffer does not contain enough encoded data.

InvalidMagic

Encoded header contains invalid magic value.
First four bytes must contain b"qoif".
This usually indicates that buffer does not contain QOI image.

InvalidChannelsValue

Encoded header contains invalud channels number.
QOI supports only images with 3 or 4 channels.
Any other value cannot be produced by valid encoder.

InvalidColorSpaceValue

Encoded header contains invalud color space value.’ QOI supports only images with SRGB color channels and linear alpha (if present) denoted by 0 and all linear channels denoted by 1.
Any other value cannot be produced by valid encoder.

OutputIsTooSmall

Output buffer is too small to fit decoded image.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecodeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DecodeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DecodeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl Hash for DecodeError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<DecodeError> for DecodeError

fn eq(&self, other: &DecodeError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
